COKlNG-OVEN..

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed September 19, 1904. Serial No. 225,104.

To LZZ whom, it mln/y concern,.-

Be it known that we, FRANZ PALLENBERG and FRIEDRICH WILHELM SANDMANN, citizens of the German Empire, and residents of Dortmund, German Empire, have invented new and useful Improvements in (joking-Ovens, of which the following is a full, clear, and exact description.

The present invention relates to coking ovens or furnaces with vertical heating-fines in which the gas-feed takes place beneath the furnace-wall through one or more ducts or passages. In such furnaces as heretofore made the nozzles or jets may be removed for examination either through an opening at the upper part of the furnace or downwardly through the gas-distributing passage underneath the furnace-wall.

In the accompanying drawings, Figure 1 is a vertical section through a part of the cokingoven according to the present invention, and Fig. 2 is a section taken partly on lines A B and C D of Fig. l.

The coking oven or furnace is so constructed that each vertical iue a is provided with its own nozzle or jet L. The gas is fed tothe jets 7) through channels c, which are arranged beneath the iiues a. The said jets b may be accessible through openingsf, which establish communication between flues a and the passages (Z, arranged laterally of the gas-distri buting passages. Each opening'r may be closed by a stopper or plug e, so that the communication between the passages may be shut off. On removing the stopper or plug the nozzle or jet may loe laterally withdrawn for examination or for other purposes. Opposite to each opening f, but at a higher level, is arranged an opening l1., which may be'rcgulated by a slide or damper g. Through this opening L air is admitted from the channels to the iues a. The slides or dampers g are accessible through the said openings lffrom the passages d, so that the supply of air necessary for combustion may be regulated. By controlling the air and gas supply in each vertical flue an economical combustion can be obtained in each iiue.

We claim as our invention 1. In a coking-oven the combination of vertical lues, gas-distributing channels beneath the said ilues, jets for feeding gas to the said flues, passages parallel to the gas-distributing channels, means adjustable from said passages for introducing air into the lues,

openings connecting the said fines and passages and rendering the said jets accessible, and means for closing the said openings, substantia'lly as described.

2. In a eokingoven the combination of vertical flues, gas-distributing channels bcneath the said flues, jets for feedinggas to the said iues, passages parallel to the gas-distributing channels and communicating with the iiues by openings, stoppers for closing the said openings, openings for feeding air from channels into the fines, slides for regulating the air-supply, substantially as described.

In testimony whereofl we aflix our signatures in the presence of two witnesses.
